What I'm looking for

I'm looking to build reliable production AI systems, especially agentic workflows, LLM applications, and enterprise integrations that solve complex real-world problems.

At Reputeo, I design and develop deep agents for SOC analysis, building multi-step reasoning, prompt engineering, tool development, and integrations for automated threat detection and incident response.

I've built specialized incident-triage sub-agents, integrated security platforms for cross-platform analysis, implemented PII masking with 100% precision and ~99% recall, and fine-tuned an LLM for natural-language-to-Elasticsearch query generation.
